SERIMUX-CS-16: 16-port console serial-port switch 

SERIMUX^® Console Switch gives IT managers the ability to cost effectively manage serial devices, including servers, switches, routers, and telecom gear. The switch is controlled via an ASCII terminal with menu-driven integrated software, or by the front panel keypad.

Features and Benefits
• Eliminates the need to connect each device to an ASCII terminal or PC
• Connect up to 8 devices with different baud rates, parity, and character length. Each switch also has one RJ45 connector for the local terminal
• Provides out-of-band access to network devices (servers, routers, network switches, and any other network devices allowing console operation using RS232)
• No inadvertent "break" signals are generated to cause unintentional rebooting of SUN computers
• Available with an optional 48V DC-DC power converter for telecom environments
• Connects to console serial ports using standard CAT5/5e/6 cables and cable adapters. Maximum cable length is 100 feet
• Two operator levels (administrator and user)
• Switching is simplified with programmable device names and menu-driven device selection
• Built-in data buffers save the most RS232 console output from each connected device, which simplifies troubleshooting failures
• Local commands can be directed via VT52, VT100, ANSI serial console, a PC with a terminal emulation program, or any compliant terminal
• Gain access to servers without interrupting service to end-users; maintain optimal up-time
• Manage server farms or data centers via serial ports and standard external modems
• 1RU rackmount case is standard
